摘要
成都市新津县拦河闸位于成雅高速公路岷江大桥下游450 m处,闸基红层中石膏发育,表层岩体中石膏溶蚀强烈,岩体透水性强,通过钻孔、物探声波及电视录像研究石膏层分布特点,溶蚀程度及深度,并结合工程具体情况分析对工程的影响,提出处理意见,为同类工程研究和处理提供参考。
The Xinjin Gate is located in 450m downstream the Minjiang bridge of Chengya highway.The gypsum is developed in the red bed,the corrosion is heavy at the top rock mass,and the water permeability of the rock is high.This paper studied the distribution characteristics,corrosion degree and depth of the gypsic horizon by drilling,geophysical sound and television recording,analyzed the influence on the project,and gave prevention measure,which may provide the reference for the similar project.
